The instructions below assume correct root prim alignment. If not, you will probably be driving sideways or upside down.

Before the ACS scripts will operate, you must set the permissions to no modify and no transfer on the individual scripts. It's best to do this in your inventory or the original packaging (or Mechanic HUD if you are injecting), so that you do not need to set them every time.

It's also important to know that if you make changes to the scripts, do not edit or save them directly into your avatar inventory, or they will not compile. You must edit/save them in a vehicle (or any prim) directly. Then you can copy your edited versions back to your inventory for safekeeping.

Do not be overwhelmed by the script options and features. The following four-step install will get you up and running. You can dive into other options if you need them.

ACS Install

Place scripts from Root Prim Scripts box into your vehicle's root prim along with at least one animation file.

If permissions are set properly on the scripts, and at least one animation is in the root, the vehicle is ready to drive.Reboot the vehicle from its menu, give it a couple seconds and then and drive.

From the vehicle menu choose > Position and adjust the seating position.

That's it. You can add more options as you need them. If your vehicle contains mesh parts, make sure the mesh keyword is added to one of the prim names in the linkset so the script knows to use mesh physics settings.

If you want to connect the Mechanic HUD for advanced functions, you can drop in the +Mechanic Tool Script+, and then while wearing the HUD, touch the vehicle to connect it.

To use your vehicle as a boat, at the top of the Root Settings script you must set the B_Mode parameter to TRUE. See the article on additional settings for boats.

You will likely prefer to use the included Mariner engine mod for boats, as it uses a cruise-control system and introduces special new banking controls more suitable for boats than the standard ACS engine.
